Brawl Royale

Brawl Royale is a Flash game created by Matt Roszak in 2008. The player takes control of Matt in a quick-draw competition; the player must press the Space Bar to attack and defeat the enemy before they do the same to Matt. With each successive round, the opponents' reaction time becomes quicker, forcing the players to react even more quickly. There is also a two-player mode, where the second player takes control of Lance with the Enter key.

Relation to the Epic Battle Fantasy series

The final boss of Brawl Royale - a zombified Goku - returns as the final boss of Epic Battle Fantasy, looking even worse for the wear than before. His new injuries seem to be a result of Matt's strike against him in Brawl Royale.

The Red Mage returns as the first shopkeeper in Epic Battle Fantasy 2. He is called a "former rival", referencing to his duel here.

NoLegs appears atop the King Slime in EBF - assuming that he survived Matt's blow, his appearance as a boss may be an attempt to avenge his defeat in Brawl Royale.

On the other hand, several details of Brawl Royale conflict with the Epic Battle Fantasy series:

In Brawl Royale, Natalie displays no magic abilities, instead using a katana and shuriken to fight.

The attack Matt uses to defeat Natalie may have been downsized and recolored for Matt's recurring Holy Sword/Seiken skill and the one used against Black Waltz for Light Blade.

Trivia

NoLegs' bandaged appearance and choice of weapon in Brawl Royale are likely a reference to The Kitten Game.

The Tonberry is a recurring enemy from the Final Fantasy series. This particular Tonberry is wearing the helmet of Pyramid Head, a well-known monster from the Silent Hill series.

Black Waltz hails from Final Fantasy VIII. He has appeared previously in some of Matt Roszak's animations, including No Name and FF Battle.

Yoko Littner is a character from the Tengen Toppa Gurren Lagann anime. Her appearance in Brawl Royale is mainly based on her combat outfit during the Mugann invasion of Kamina City, but her boots appear inspired by the outfit she wears when the Dai-Gurren Brigade sets off into space to confront the Anti-Spirals.
